' Virginia N. Y., a corporation of Application March 16, 1932. Serial No. 599,090 3 Claims. (01. 255-51) This invention relates to percussive tools and carriers therefor.

An object of the invention is to provide a portable rig or outfit carrying a plurality of percussive tools which may be operated in unison or singly, as desired, and moved quickly from place to place or progressively along a job, in a minimum amount of time, as well as requiring a relatively small number of operators in attendance, thereby permitting a maximum amount of work to be performed in a minimum amount of time, and at greatly reduced cost.

With these and other objects in view, as may appear from the accompanying specification, the invention consists of various features of construction and combination of parts, which will be first described in connection with the accompanying drawings, showing rig of the preferred form embodying the invention, and the features forming the invention will be specifically pointed out in the claims. 5

In the drawings: Fig; 1 is a side elevation of the portable per cussive tool carrying apparatus.

Fig. 2 is an end view of the apparatus; Fig. 3 is an enlarged detail end view of the apparatus. I

Fig. 4. is an enlarged detail in perspective of the tool mounting. I Fig. 5 is a detailed View of the manifold which supplies the operating fluid to the various percussive tools.

Fig. 6 is a side elevation of a percussive tool as employed in the apparatus. Fig. 7 is a side elevation of a modified form of the apparatus. a o

Fig. 8 is a side elevation of a further modified form of the apparatus. Referring more particularly to the drawings, and with particular reference to the form of the portable tool carrying apparatus disclosed in Figs. 1 to 6, inclusive, of the 1 of any approved type is illustrated, which has anextension body or frame 2 thereon. A platform 3 is supported upon the frame 2 in any suitable manner, and a tool supporting railing 4 is carried by the platform 3. The railing 4: comprises the longitudinally extending horizontal sections 5 and the end cross braces 6. An operatorsupporting platform '7 is supported by the railing 6, and this platform '7 may be formed of hingedly connected sections, to permit its ready removal if desired.

The longitudinally extending side bars 5 of the brackets 3 mounted a portable percussive tool or specific type drawings, a motor truck' thereon. The tool carrying brackets 8 may be of any preferred form of adjustable bracket for supporting percussive tools, various types of these brackets being in common use and upon the market. The bracket 8 is so constructed asto, permit adjustment of the tool carrying cradle 9 vertical- 1y, at various angles about a horizontal axis transversely of the longitudinal axis of the tool, as well as adjustments of the tool at various angles about an axis parallel with the longitudinal axis of the tool.

The tools 10 which may be of any preferred form of percussive or fluid operated tools, are slidably carried by the cradles 9, to permit feeding of the tool to the work to be performed.

In the drawings, automatic or fluid feed rock drills of the type disclosed in U. S. Letters Patent 1,611,334., 1,658,138 and 1,658,139, are illustrated, and while this particular type of tool is particularly adaptable for certain kinds of drilling, it is to be understood that the present invention is not limited in any way to a particular of pneumatic or percussive tool, but that various types of such tools, for instance, hand or manual feed rock drills, paving breakers, stopers, tampers, or any of the various approved types of tools on the market, may be employed without departing from the spirit of the invention.

The cradle 9 is illustrated as havinga drill bar hole-spotting guide 11 attached thereto, which engages the drill bar 12 for properly guiding the drill bar during drilling movement.

The fluid which operates the various tools 10 is supplied to the tools through the usual type of hose connection l l, which hose connection is in-turn connected to a manifold or receiver 15 carried by the supporting platform 3. A lubricator 16 and a valve 17 are connected in each of the operating fluid supply lines to the individual tools 10, so as to permit operation of all of the tools carried by the truck body, either in unison or independently of each other, as desired.

The manifold or receiver 15 has a fluid supply connection 18 connected thereto, which in turn may be connected to any suitable type of compressor, for providing fluid under pressure, for operating the tools 10. The manifold or receiver 15 is of a capacity greater than the amount of compressed fluid required to operate all of the tools, so as to provide an auxiliary storage receiver and prevent stalling or stoppage of the tools, due to imperfect feeding of pressure fluid thereto, during their operation.

The manifold or receiver 15 may be positioned at any convenient point, but preferably beneath the platform '7 and the space upon the platform 3 about the manifold or receiver 15 may be used for tool storage or for any other purpose desired.

A supporting frame 19 is provided which may serve as a canopy or top support.

In Fig. 2 of the drawings, guiding pulleys 22 and 23 for the hose 14 are shown, and they may be employed, if it is found desirable. The pulleys 23 are rotatably supported by the frame 4, while the pulleys 22 are rotatably supported by brackets 24:. The brackets 24 have counter weights 25 connected thereto, which are in turn connected to suitable flexible members 26, which extend over pulleys 27. The counter Weights 25 are provided to prevent kinks in the hose 14.

By mounting a plurality of the percussive tools 10 upon the frame 4 carried by the truck 1, a mobile or portable rig is provided, which can be readily transported from place to place, and in instances where considerable drilling is to be done, the gang of tools may be moved progressively along the job with minimum effort, it only being necessary to move the truck from one position, after the desired number of holes has been drilled, into the next position where it is desired to drill, the tools being already set and positioned for drilling, thereby saving much valuable time and labor and very greatly facilitating the drilling operations.

Through the medium of the brackets 8 the various tools may be adjusted to any desired angles, and by means of the valves 1'7 any part or all of the entire gang of tools may be operated at any time. The manifold 15 is provided with the usual approved type of drain cook 21.

In the forms illustrated in Figs. 1 to 6, inclusive, of the drawings, the compressed or pressure fluid used in .operating the tools is provided from a source outside of the portable unit, and it may be desired, in some instances, to provide a complete unit including not only the power for moving the unit but also suitable compressing means for compressing the fluid used in the operation" of the tools.

In Fig. 7 of the drawings, such a unit is shown, and while a tractor of the track-laying type is shown, it is to be understood that any suitable type of tractor, truck or the like, may be provided, without departing from the spirit of the present invention.

In Fig. '7 of the drawings, the tractor 30 comprises the usual approved type of engine or motor structure 31, which operates the propelling track 32 of the tractor. The frame 33 of the chassis of the tractor is extended rearwardly, and it carries a compressor 34 of any approved type, which is driven through the medium of any suitable type of power transmitting mechanism 35, from the engine 31 of the tractor. In (his form of portable, drill or percussive, tool rig, the compressor 34 discharges into a suitable receiver 36, which receiver in turn delivers the compressed fluid to the manifold 37. The manifold 3'7 has individual branch connections 38 with the various tools 39. Like in the previously described form of the invention, each of the connections 38 may have valves therein to permit individual cuttingout of any of the tools 39 of the gang, if desired. The manifold 37 has a capacity greater than the amount required for maintaining the various tools 39 in operation, so as to provide a reserve to insure continuous operation of the tools when desired.

The tools 39 may be supported by the tool supporting railing 4.0 through the medium of suitable adjustable brackets such as the brackets 8 previously described, and while automatic feed tools are shown in this form illustrated in Fig. 7, it is to be understood that any suitable type of percussive tools may be employed, without departing from the spirit of this invention.

In Fig. 8 of the drawings, a still further form of the invention is shown, and this construction provides a trailer or portable unit which is transported by outside power, that is, the portable unit itself does not embody a motor or other power for propelling it. 1

This construction illustrated in Fig. 8 of the drawings comprises a portable frame 50 which is supported upon suitable wheel-carrying axles 51, and has a coupling 52 to facilitate its connection with any suitable type of p opelling means. A prime mover or motor 53 of any suitable type, such as an internal combustion engine, is carried by the frame 50, and it is connected through any suitable power-transmitting mechanism 53' with a compressor 54. The compressor 54, which may be of any approved construction, discharges into a manifold receiver 55. The manifold receiver 55 is similar to the manifolds l5 and 37, .and itis carried by the frame 50 beneath the platform 56 which is supported upon the railing 57. The manifold 55 which acts as the receiver of the compressed fluid, has any desired number of percussive tools 53 connected thereto, by individual hose or other suitable connections 59. If it is so desired, in this last form ,of unit, the usual type of receivers such as shown in the form illustrated in Fig. 7, may be employedwithout departing from the spirit of the present invention, and it is also to be understood that the manifold used with the construction shown in Fig. 7 may be of such size as to serve as-the receiver, if desired,

without in any way departing from the spirit of the present invention.

From the foregoing description, taken in connection with the accompanying drawings, it will be apparent that a portable rig or outfit for carrying a plurality of percussive tools, and the combination of such outfit'with the tools, has been provided, which will permitadjustment of the various tools to the desired drilling angles or positions, it being understood that the. brackets 8 are movable along the railing 4, as well as about the railing, and movement of a plurality of such tools, properly adjusted, from place to place, eliminating resetting of the tools upon each movement or after the drilling of one set of holes; also, that owing to the manner of mounting and operation of the various tools, a minimum number of operators will be required. for controlling the operation of a plurality of the tools.

Furthermore, rapidity in large drilling or working operations, wherever percussive tools are employed, will be greatly facilitated through the operation of the gang or plurality of tools in unison, and the ready portability of such gang of tools.
